Canning Altitude by Canadian City (Find Your Band)
Your canning altitude band depends on your city's elevation. Bernardin and Health Canada use four water-bath bands: Band 1 is 0 to 305 metres (use the base recipe time), Band 2 is 305 to 610 metres, Band 3 is 610 to 1220 metres, and Band 4 is above 1220 metres. Most Canadian cities — Vancouver, Toronto, Montreal, Halifax, Winnipeg, Ottawa — sit in Band 1 and need no adjustment. Saskatoon, Regina, Kelowna, and Kamloops fall in Band 2. Calgary, Edmonton, Lethbridge, Red Deer, and Whitehorse are Band 3. Banff and Canmore are Band 4. The band is what matters, not the exact metre — and the band tells you which Bernardin time addition to add to the recipe's base processing time. For pressure canning you raise the pressure instead of the time.
If you live anywhere above about 305 metres in Canada, the processing time printed in a canning recipe isn’t enough on its own — water boils cooler where you are, so you add time (water-bath) or pressure (pressure canning). This page is the quick lookup: find your city, find your band. For how and why it works, see the main altitude-adjustments guide.
The band is what matters, not the exact metre. Elevations below are approximate (they vary across any city) and drawn from Natural Resources Canada / Statistics Canada data. If you’re near a boundary, round up to the higher band. For the actual extra minutes, open your edition of Bernardin — we don’t invent those numbers.
The four Bernardin bands (water-bath canning)
| Band | Elevation | Action |
|---|---|---|
| 1 | 0 – 305 m | Use the base recipe time |
| 2 | 305 – 610 m | Add the Bernardin Band 2 increment |
| 3 | 610 – 1,220 m | Add the Bernardin Band 3 increment |
| 4 | 1,220 m + | Add the Bernardin Band 4 increment |
Band 1 — no adjustment needed (0–305 m)
Most Canadians live here. Use the recipe’s base time as printed.
- Vancouver (~0–70 m) · Victoria (~23 m)
- Toronto (~76 m) · Ottawa (~70 m) · Hamilton (~100 m) · Kingston (~93 m) · Windsor (~190 m) · London, ON (~250 m)
- Montréal (~36 m) · Québec City (~98 m)
- Halifax (~145 m) · Fredericton (~20 m) · Moncton (~25 m) · Charlottetown (~50 m) · St. John’s (~45 m)
- Winnipeg (~239 m) · Thunder Bay (~200 m) · Sudbury (~270 m)
- Yellowknife (~206 m)
Band 2 — add the Band 2 increment (305–610 m)
Much of southern Saskatchewan and the BC interior valleys.
- Saskatoon (~481 m) · Regina (~577 m) · Prince Albert (~430 m)
- Kelowna (~344 m) · Kamloops (~345 m) · Penticton (~344 m) · Vernon (~390 m) — all just over the Band 1 line; treat as Band 2
- Prince George (~575 m)
- Brandon, MB (~409 m)
Band 3 — add the Band 3 increment (610–1,220 m)
Most of Alberta and the southern Yukon.
- Calgary (~1,045 m) · Edmonton (~668 m) · Red Deer (~905 m) · Lethbridge (~929 m) · Medicine Hat (~717 m) · Grande Prairie (~669 m)
- Cranbrook, BC (~940 m)
- Whitehorse (~706 m)
Band 4 — add the Band 4 increment (1,220 m +)
The Rocky Mountain towns.
- Banff (~1,383 m) · Canmore (~1,309 m) · Lake Louise (~1,540 m)
If your town isn’t listed
Look up your elevation (Natural Resources Canada’s Canadian Geographical Names, Statistics Canada, or your municipality’s open data) and match it to the band table above. When you’re close to a boundary, use the higher band — a few extra minutes is never the unsafe choice.
Pressure canning is different
Everything above is for water-bath canning, where altitude adds time. For pressure canning, altitude adds pressure (PSI), not time — see the main altitude guide for the PSI side, and your canner’s manual.

Frequently asked questions
Do I really need to adjust canning times for my altitude?
Yes, if you live above 305 metres (about 1,000 feet). Water boils at a lower temperature as elevation rises, so heat takes longer to do its work in the jar, and the recipe's base time — which assumes sea level — is no longer enough. Most Canadian cities are in Band 1 (under 305 m) and need no change, but most of Alberta, much of Saskatchewan and the BC interior, and all of the mountain towns do. Skipping the adjustment where it's needed is a genuine safety gap, not a quality nicety.
My city isn't on the list — how do I find my band?
Look up your community's elevation (Natural Resources Canada's Canadian Geographical Names database and Statistics Canada both publish it, and your municipality's open-data page often does too), then match it to the bands: 0–305 m is Band 1, 305–610 m is Band 2, 610–1220 m is Band 3, above 1220 m is Band 4. Elevation varies across a city, so if you're near a band boundary, use the higher band to be safe. The band is what matters — you don't need the exact metre.
Where do I get the actual extra minutes for my band?
From your edition of the Bernardin Complete Book of Home Preserving, or Health Canada's food-safety pages. Each recipe lists a base time plus the additions per band — we don't reproduce those numbers here because they're tied to specific jar sizes and are updated over time, and the safest place to read them is the current tested source. This page just tells you which band your city is in; Bernardin tells you the minutes.
Does altitude change pressure canning too?
Yes, but differently. For pressure canning you increase the pressure (PSI / pounds), not the time. Bernardin publishes a separate PSI-by-altitude table. Below 305 m you use the recipe's base pressure; above that you step it up by band. The processing time stays the same. See the main altitude-adjustments guide for how the pressure side works.
